Can I check if a view exists on the screen with KI

Question

I am making a "before each" step and I am wanting to do steps to logout. I can't find anything about checking if an element exists before I try to touch it, then if it doesn't exist do something else. Is it possible to do this with KIF without having a reference to the object I want to check for?

Something like:

if([tester elementExistsWithAccesibilityLabel:@"backButton"])
{
    [tester tapViewWithAccessibilityLabel:@"backButton"];
}
else
{
    [tester tapViewwithAccesibilityLabel:@"Logout"];
}

Answer 1

I made this function that seems to do the trick in a pinch, but it would have some issues if multiple integration tests were simultaneously relying on the global default timeout. So far, seems to work for me.

static CGFloat CPKIFDefaultTimeout = 2

- (BOOL)elementExistsWithAccessibilityLabel:(NSString *)accessibilityLabel {
    [KIFTestActor setDefaultTimeout:0.0];
    BOOL result = [tester waitForViewWithAccessibilityLabel:accessibilityLabel] ? YES : NO;
    [KIFTestActor CPKIFDefaultTimeout];
    return result;
}

You could try something like this:

@try {
   if([tester waitForViewWithAccessibilityLabel:@"backButton"])
   {
      [tester tapViewWithAccessibilityLabel:@"backButton"];
   }
@catch (NSException *exception )
{
   [tester tapViewwithAccesibilityLabel:@"Logout"];
}
@finally 
{
   NSLOG(@"User logged out.");
}
